Getting a sore throat, cough, runny nose or flu-like symptoms in Bali can quickly disrupt your holiday. Most respiratory infections are mild and improve with rest and supportive care, but some require medical assessment—especially when symptoms are severe, worsening, or affecting breathing.
Common Symptoms
Respiratory infections can cause:
- Sore throat
- Cough
- Runny or blocked nose
- Fever or chills
- Headache
- Muscle or body aches
- Fatigue
- Sometimes nausea or other symptoms
Influenza often has a more sudden onset, with fever, body aches, fatigue, headache and cough, although not everyone with flu develops a fever.
In tropical regions such as Bali, influenza can circulate throughout the year, so getting flu-like symptoms outside the usual winter season does not rule out influenza.
Cold, Flu or Something More?
Not every sore throat is influenza.
Most respiratory infections in travellers are caused by viruses, including common cold viruses, influenza and other respiratory viruses. Bacterial infections can also occur, including some cases of streptococcal throat infection or pneumonia.
The symptoms can overlap, so a doctor may need to examine you—particularly if symptoms are severe or you have risk factors for complications.
What Can You Do at Your Hotel?
For mild symptoms:
Rest and sleep well. Your body needs time to recover.
Stay hydrated. Drink regularly, particularly if you have fever or are sweating more than usual.
Treat uncomfortable symptoms. Depending on your situation, appropriate medication may help with fever, pain, nasal congestion or sore throat.
Reduce close contact with others. If you are sick, avoid sharing drinks and utensils, wash your hands frequently and consider wearing a mask when around other people. CDC recommends staying away from others when sick with flu-like symptoms.
You don’t necessarily need antibiotics. Most respiratory infections are viral, and antibiotics do not treat viruses.
When Should You See a Doctor?
Consider medical assessment if:
- Fever is persistent or concerning
- Symptoms are getting worse rather than better
- You have severe or worsening sore throat
- You have difficulty swallowing fluids
- Your cough is becoming significantly worse
- You have persistent vomiting or dehydration
- You have an underlying medical condition that could increase your risk of complications
- You are pregnant, elderly, immunocompromised, or travelling with a young child
For uncomplicated respiratory infections, many people recover without medical treatment. However, people at higher risk of severe influenza may benefit from early antiviral treatment, which works best when started as soon as possible.
🚨 Don’t Ignore These Warning Signs
Seek urgent medical care if you develop:
- Difficulty breathing or shortness of breath
- Chest pain or pressure
- Confusion or difficulty staying awake
- Severe weakness or unsteadiness
- Severe dehydration or very little urine
- Seizures
- Symptoms that improve and then suddenly become worse
These can indicate a more serious respiratory infection or complication such as pneumonia.
Why Travellers in Bali Shouldn't Ignore a Fever
A fever during travel can have many causes. While a cough and sore throat may suggest a respiratory infection, fever should not automatically be attributed to flu.
Your doctor may consider your recent activities, travel history, exposures and other symptoms when deciding whether testing or further investigation is appropriate. CDC specifically recommends telling healthcare providers about your travel and activities when seeking medical care.
What About Flying With a Respiratory Infection?
If you are feeling significantly unwell, consider postponing non-essential travel and getting medical advice first.
CDC advises people with flu symptoms to stay home and away from others until their symptoms are improving overall and they have been free of fever without fever-reducing medication for at least 24 hours.
If you must travel, take precautions such as wearing a well-fitting mask, practicing hand hygiene and avoiding close contact with vulnerable travellers.
Need a Doctor at Your Hotel?
If you are too unwell to travel to a clinic but your symptoms are stable, a doctor home or hotel visit can be a practical option in Bali.
A doctor can assess your symptoms, check vital signs, examine your throat and lungs, determine whether testing may be useful, and advise whether you can safely continue recovering at your accommodation or need further medical care.
Know the warning signs, rest early, and don’t wait if your breathing or condition starts to worsen.
